AEP Milton Nas is retired. EIA's monthly generator inventory (EIA-860M, August 2026) lists every generator at this battery storage plant as retired; the last one retired in April 2021. It is not counted among West Virginia's operating plants or in any ranking on this site.
The figures below describe the plant when it ran: equipment from EIA Form 860 (2024).
The 2.0 MW is nameplate capacity: the most this plant's generators are rated to produce, not what it actually generates. EPA eGRID reports no positive net generation for it this year.
How it works
Why the numbers look like this: every charge-and-discharge cycle loses some energy as heat, so a storage site usually reports slightly negative net generation: it takes in a little more than it gives back. Its job is timing, not making energy.
This plant highlighted in navy-ringed pin; other generators within 25 miles shown as fuel-colored dots.

Battery storage facilities don't generate electricity — they store it. They charge from the grid (often from solar during the day) and discharge during peak demand or to firm up renewables. EIA classifies them as power plants because they connect to the grid like one.
